Thanks for coming up with this utility, it's a great need but this fails even with simplest examples I can't see how I'd trust this on production.

bs_2 = b'Carter\xe2\x80\x99s Janitorial'
chardet.detect(bs_2)
{'encoding': 'Windows-1252', 'confidence': 0.73, 'language': ''}
bs_2.decode('cp1252')
'Carter’s Janitorial'
bs_2.decode('utf-8')
'Carter’s Janitorial'

am I doing something wrong? it's just couple of characters and it's clearly utf-8.
